IndexKinds of relief model Fluvial model (rivers) Torrential model (torrents) Glacier model (glacier) Karstic model (subterranean water) Litoral model (swell) Eolic model (wind)
Fluvial model Form narrow pass, flood plains and wave-cut platform. This areas are very goods for the farming and the human occupation. Form valleys with “V” In Spain this kind of erosion is very frequent.
Fluvial model Narrow pass river Cares (Picos de Europa)
Fluvial model Flood plains (River Pas and Narcea)
Torrential model It type of relief model is very erosive and origin beautiful landscapes. Origin relieves like canyons and carcavas. When are accumulated the erode materials form alluvial fans erosions. They aren´t good areas for the population and farming.
Torrential model Carcavas Tabernas desert (Almería)
Torrential model Almadenes Canyon (Cieza) Río Lobos Canyon (Soria)
Torrential model Waterfalls and rapids. They are very frequents in high mountains.
Torrential model Ravines and narrow pass. The aggressive erosion origin for the water and the materials that the water bring, form the ravines.
Glacier model This kind of model is origin in high mountains areas, very colds zones. The human occupation is very small and this areas normally are touristic. The glacier valley has got “U” form and it has got quite population. Form glacier cirques and other forms.
Glacier model Glacier cirques. Origin for the accumulation of ice.
Glacier model “U” form valley origin form the weight of the block of ice.
Glacier model Glacier lake. Typical in post-glacier landscape
Glacier model Erosion in rocks. The water infiltrate in the rocks, and when is freeze, this water occupy more, and the rock is broken.
Karstic model In areas forms for limestone or plaster, the water infiltrate in crack, and it dissolving the rock and form galleries and caverns. There are two types: - Superficial: origin form the dissolution and the roof of the cavity like dolines. - Subterranean.
Littoral model The swell is an agent very erosive. When the swell is more aggressive form cliffs, capes and ledges. When the swell is not very aggressive form beaches, the place where the eroded materials are accumulated. When the cliffs are eroded form abrasion platforms.
Eolic model In Spain this model is not very important, but the wind transport the sand accumulated in the beaches, origin coastal dunes. Is predominant in deserted zones. When the wind carry the sand and the clay form rocky deserts. When there are sedimentation of sand, is origin dunes field.
Eolic model The particles in the wind origin corrosion in rocks so the rocks have got different shapes.
